This invention relates to an anti-skidding i device particularlydesigned for use upon motor vehicles ernploying pneumatic orfeushe (ion tires.

An object, is provide-an 'ant-iQskid as; vice which may be quickly and conveniently attached to or detached from connection with the wheel structure, for use on muddy or sandy roads, or wet or 10y pavementsor roads. -s v v Another object is. to provide a substantially U-shaped hinged structure for at taching, or connecting tothe rim of wheel structure so as to facilitate the mounting upon and removal from a tire of flexible tire" chain. 7 v

f A still further object of the invention is toprovide in agsu'b'stantially L -shaped [hingedly joined. anti-skidding device a coil engaging" means, preferably an ordinary spring, means whereby, when the U-sliaped, device ispositioned on the rim structure, the:

sidearmswill} be drawn into sustaining en-- gagement with rim structure topermit ad justing tread n eans about the wheel; tire and'engaging the same-with the U-shaped device; i still further objaect ofthe invention is i to provide, in a substantially U-shapedl l ingedly oined a1 1ti-skidding device a' loekthe tread means, whereby when the ill-shaped. deviceiis positioned on the rim: structure and the tread meansis adjusted about the wheel V sidearm of the V U shaped devicef and also plied thereto;
